This variable provides the reason, if any, that the Court gives for granting the petition for certiorari. If the case did not arise on certiorari, this variable will be so coded even if the Court provides a reason why it agreed to hear the case. The Court, however, rarely provides a reason for taking jurisdiction by writs other than certiorari.
